Abstract

A purifier for running water and drinking water of the utility model provides a drinking water purifier which is connected to the running water and adopts a method of ozone and active carbon. The running water passes a pre-filter (2) for filtering the sediment suspension, and then enters into a gas-water mixer (3), which inhales the gas with ozone prepared by an ozone generator (8) to mix with water, so the ozone is dissolved in the water, during the process that the water with ozone stays in a water containing cavity (4) in a post-filter (7), the water is purified treated by the ozone, and then the water is filtered through filter cores (6) of a porous medium absorption material (such as active carbon), the harmful chemicals in the water is absorbed and removed, and the rest ozone in the water is removed, finally the high quality drinking water flows out. As most harmful chemicals in the water are oxidative decomposed by the ozone, and the ozone also has the effect of regenerating the active carbon, thereby greatly improving the life of active carbon.

Description

Tap water purifying of drinking water device

The utility model relates to a kind of tap water that is connected in, and handles with ozone purification, adds the purifying of drinking water device that activated carbon filtration is handled again.

Because the influence that industrial and agricultural production and life produce, make the water source of people's tap water be subjected to pollution in various degree, particularly organic carcinogenic contaminant increases, impel the waterworks to adopt gac to add ozone process and carry out the tap water processing, but because facility investment is big, the working cost height has only obtained employing in developed country and city.

At the existing many kinds of purifier of family and microcommunity use, the water that the reverse osmosis method water purification machine is produced, the quality height, steady quality, but involve great expense the expense height.Now generally adopt gac (or molecular sieve) filter element filtering method treating water, utilize the micropore in the gac, the absorb polluted matter molecule, in case but charcoal absorption saturated after, just no longer include detergent power, thereby have life problems, must be often renew cartridge more.Ozone has extremely strong oxidation capacity, can not only kill various bacteriophagees, can also decompose detrimental substance, but purify waste water with ozone merely, the chemical nuisance in the treating water, required ozone dosage is too big, to some organism, oxidation time is long, and ozone concn requires high, directly drinks the mouth of a river ozoniferous and feels bad.Adopt ozone to add process of active carbon, earlier ozone is added in the entry, water is carried out ozonation treatment, handle through activated carbon filtration again, such process for purifying water, more scientific and reasonable: 1, ozone plays the effect of kill bacteria virus, to the water disinfection; 2, harmful chemicals in ozone and the water (organism or inorganics) carry out chemical oxidation reaction, the nuisance that those are easily decomposed by ozone oxidation, at first removed by ozone oxidation, significantly reduced the burden of later stage activated carbon adsorption, improved the active lifetime of gac, those larger molecular organicses, become small organic molecule by ozone oxidation, be easier to, thereby improved the water purification quality by charcoal absorption, ozone in the water is through gac, ozone is by charcoal absorption, and ozone that is adsorbed and the organism that is adsorbed reaction consume the organism that is adsorbed, play active regeneration effect like this to gac, improved the active lifetime of gac, moreover, through the water of activated carbon filtration processing, ozone is filtered, and mouthfeel is better.

The purpose of this utility model is to propose a kind of tap water that is connected in, be fit to the purifying of drinking water device that family and microcommunity are used, it has adopted elder generation to handle with ozone purification, again the method that purifies through activated carbon filtration, improve drinking water quality, improve the active lifetime of gac.

The utility model is achieved in that major parts includes: inlet valve, fore filter, ozonizer, gas-water mixer, post-filter.The main effect of fore filter is filter to remove solid particulates such as silt in the water, suspended substance, after the tap water process fore filter filtration treatment, enter gas-water mixer, in gas-water mixer, water mixes with the ozone gas that contains by the ozonizer manufacturing, make ozone solution in water, earlier water is carried out purifying treatment by ozone, water ozoniferous enters post-filter, the absorption filter core that the gac class is arranged in the post-filter, effusive water after post-filter is handled just can reach high-quality tap water.

Feature of the present utility model is: ozonizer adopts corona method, is that raw material is made ozone with air, and the corona component of ozonizer adopts plank frame or concentric tube type structure; Gas-water mixer adopts jet injection mixed structure, include fluid orifice, injection mixing section, utilization jet injection mixing principle, water under pressure, form high-speed jet through fluid orifice, high-speed jet causes violent turbulent flows in the injection district, the injection suction forms negative pressure, the ozone gas that contains of ozonizer manufacturing is sucked, mix with water, the effect of injection mixing section is not will contain the ozone gas suction simply to mix with water, importantly strengthens to contain ozone gas and water blended effect, makes ozone be dissolved in the water fully effectively; Post-filter includes filter core and water containing chamber, and there is the ventilating pit that communicates with atmosphere the upper end of post-filter, and water containing chamber is arranged on the upper reaches of filter core, and the effect of water containing chamber has; 1, prolongs the residence time that contains ozone water, promptly prolong the reaction times of nuisance in ozone and the water, fully effectively utilize ozone the water purification ability; 2, gas-water separation, water through gas-water mixer contains a large amount of bubbles, bubble in water containing chamber with water sepn, gas is discharged from the ventilating pit of upper end at last, filter core in the post-filter has adopted porous media adsorbing material (as gac, molecular sieve), and water is the resistance that overcomes filter core by the self gravitation effect of water by filter core; The open and close of inlet valve are subjected to the water level control in the post-filter, and when water level was lower than the water level of regulation, inlet valve was opened, ozonizer startup work, and when water level reached the water level of regulation, inlet valve was closed, and ozonizer is closed down.

Be provided with fore filter in the utility model, in advance the silt in the water, suspended substance are filtered and remove, reduced the ozone depletion amount that the back segment ozone purification is handled, alleviate the burden of post-filter, filter core in the post-filter is not born the filtering of silt, suspended substance, thereby the filter core aperture can be big, and the resistance that current pass through is little, and the hydraulic pressure that makes post-filter only depend on the self gravitation of internal water to produce overcomes the resistance to flow of filter core.Because there is ventilating pit the post-filter upper end, is open, the gas-water mixer outlet does not stop, produce malleation, then can actual adopt jet injection mixed structure simple in structure, the negative pressure of utilizing the jet injection to produce sucks the ozone gas that contains of ozonizer manufacturing to mix with water.Adopt the utility model to realize small-sized household purifying of drinking water device, after the employing ozone purification is handled, handle through active carbon purifying again, reach high-quality drinking-water, and one-piece construction is simple, cost is low, reliable, charcoal absorption class filter element life is long.
